Steam cost depends upon the type of boiler,fuel and steam condition like pressure,temp..etc. Considering you have an oil fired low pressure boiler with say 88% efficiency on NCV, it takes about 65kg of fuel for 1000kg(F&A 100C) of steam. Add your maitenance and depreciation and other costs which comes to rougly 20-30% of fuel costs. You can easily calculate the cost this way.
